Figure 7. Qualitative comparison on illustrative inspection cases. Columns A-F show the input image, ground truth, D-FINE^[33], YOLO26^[30], RF-DETR^[35], and CSG-YOLO, respectively. All displayed predictions were generated in this study. The references identify the compared detector architectures, rather than the sources of the images or prediction results. The displayed cases illustrate specific detection behaviors and do not establish performance across the test-set distribution.
